Betweeny the arms 12 land 14 is a bagstripper 28 1, 3r and A), theloopedA inner end of which lis slidably supportedfby a bearings()(Fig. 1) iiXed ,to theclosed end`f16'v`of the trarne member.y ',Ifheouter Vor `forward- .erid otlthelstripper isf. slidably supportedbya.bushing f carriedby an upstanding web 22 secured to one end of a rack34 which is slidably mounted between ways or guides 35 on the platform6, these guides being aligned with theslot 8. Apretractingrspring 36(Fig. 1) connects a lug SS-(Fig. 1) carried by the rack with thebracket10 so as to hold the rack and stripper in retracted position.

With the construction and arrangement thus far described an inner bag orliner I may be'manually drawn about the arms and`stripper and an outerbag O may likewise be ldrawn over the inner bag I, as shown in Figs. lto 3. Since the inner bag is somewhatlonger than the outerbag its openend projects beyond that of the outer bag, as illustrated in Figs. l and2, thus providing'a culling allowance. By pulling on the rod 25 the arm141s vswung to extended position wherein it holds the nested bags instretched, fixed position and when the pull onthe-rod 251is released thearm 14 is returned to retracted'positiom wherein `the grip on the nestedbags Ais released so Vthat the stripper 28 may be brought intooperation.

Mounted on the platform 6 in spaced relation to the arms 1 2 and "14(when the latter is extended) are guide rods 41 and 42 and at theforward ends of these rods are ysleeves 44 and 45 which are boths'lidable and rotatable on the rods. Corresponding ends of compressionsprings 46 and 48 act on the inner support for the rods and Vthe innerend of the sleeves to hold the latter in outermost position against theouter support, as shown in Figs. l 'and 2. The sleeves 44, 45 carryfollower arms 50, 51 which project inwardly toward the stretcher armsand also upstanding lugs 52 and 53 to which are adjustably securedlaterally extending cut-ling lingers 54 and 55. Tension springs 56 and57 (Fig. 1) connect the cutting arms 52 and 53 with lthe arm 12 and yoke18, respectively, vand normally hold the culling arm in verticalVposition with the follow rolls on the dwell portions ofcams 58 and 59when the parts are retracted, as shown in Figs. 1 to 3. A

The cams 58 and`59 are mounted on the platform 6 inwardly of the guiderods and their outer ends have dwell portions over which the rollers offollower arms 50, 51 ride. The construction and arrangement of parts aresuch that when the nested bags are held by Ithe stretcher arms 12 and14, as shown in Figs. l and 3, the cutting lingers are spaced from butaligned with the edges of the inner bag between the prongs ofthe forks20 and 21, and when the sleeves move inwardly the follower rolls contactthe inclinesjof the cams at which point the cuihng lingers engage theinner bag and as the follower rolls ride up the inclines of the cams thesleeves and cufling Afingers are -rotated outwardly through a slightangle, thereby drawing the material of Vthe inner bag away from theforks to initiate the culling operation. Continued inward movement ofthe sleeves causes the culling lingers to'roll or fold back the cullingallowance C about theedge of the outer bag, thus completing the cufliingoperation, at which point the lingers disengage thel culfed bag. Sincethese lingers are held tipped so long as the follower rolls ride on thethrow or salient portions of theV cams, they remain disengaged from thenested bags and hence do not interferewith the return movement of thesleeves under the influence of springs 46 and Y48; and when the followerrolls ride down the cam inclines the springs 56 and 58 come intooperation to restore theparts to their original position.

The sequential operations above described are effected by mechanismsbest shown in Fig. 2, which comprise a main drive shaft 60 suitablyjournaled in bearings (not shown) carried by the stand 1. Rotatablymounted adjacent to one end of the shaft 60 is a sheave 61 connectedthrough a conventional one-revolutionpclutch 62V to the shaft 60. Thesheave 61 is connected by a V-belt 63- with one of the two sheaves 64 ofa motor 65 which is mountedin a housing 66 secured to the stand 1. Keyedor otherwise secured to the shaft 60 are sprockets 68,

eadh positioned inwardly of a vertical plane tangent to the adjacentguide rod and between these sprockets and in approximate alignment withthe pull rod is a plate cam 7l). A follower lever 72 is pivotallysupported at 74 to a depending arm 75 secured to the stand. The innerend of this arm carries a follower roll and its outer end is connectedby a clevis'to the lower end of the pull rod 2S. Hence, counterclockwiserotation of the cam causes the follower rod to ride up on the salientportion of the cam, thereby pulling the rod downwardly to extend the arm14. If desired, the outer end of lever 72 adjacent to its connectionwith the pull rod 25 may carry a treadle rod 76 which may be manuallyoperated by a treadle (not shown) if circumstances require manualoperation of the stretcher arms.

Mounted adjacent to the opposite sides of the stand are identical drivesfor the sleeves 44 and 45 and a description of'one of the drives willtherefore s'uce. Each drive comprises a downwardly inclined arm 78 whichsupports an idler sprocket 8tlaligned with the sprocket 68 and rotatablymounted on shafts carried by the stand are sprockets 81 -Vand 82likewise aligned with sprocket 68. A chain 84 extends about `thesprockets 68, 80-"82 passing along a slot (not shown) in the platform 6and this chain carries two dogs 85 and 86 at tfhe half and full waypoints. v*Each of the dogs is L;shaped and positioned so as to engagethe outer face of the adjacent follower arm, as illustrated in Fig. 3,'and carry the associated sleeve inwardly along the guide rod 42,thereby compressing the spring 48. As Vthe dog 85 turns downwardly'about the sprocket 82 it disengages the arm 51, thereby permitting thereturn of the sleeve under the influence of the spring 48.

A sprocket 88 is secured to the approximate center of the shaft 60 andthis sprocket is connected by chain 90 to a sprocket 91 secured to shaft92 (Figs. l and 2) which is journaled in `bearings (not shown) carriedby the stand. The sprockets 8S and 91 are the same size and hence onerevolution of the former effects on revolution of the latter. A segmentgear 94 is fixed to the shaft 92, the construction and arrangement ofparts being such that the periphery of the segments projects through theslot 8 sothat its teeth are engageable with the rack 34 to carry it fromretracted position to bag stripping position. The design of the cam 70,segment gear 94 and associated parts is such that the segment gear d'oesnot come into operation until the roll of the follower arm 72 rides backon the dwell of cam 7l) oy which time the leading tooth of the segmentgear makes contact with the rack and when the cam and sprocket havecompleted one revolution so also has the segment gear which comes torest with its trailing tooth disengaged from the rack, as shown in Fig.2. A

The aforementioned sequence of operation is under the control of theclutch lock which comprises an arm 96 pivoted at its upper end to thestand'and this arm is connected to the plunger o f a solenoid 98 carriedby a bracket secured to the stand. A tension spring 99 normally holdsthe arm 96 in locking position. 'Ilhis solenoid is under the control ofa manually operated switch 100 which momentarily closes the circuit tothe solenoid when the lever 101 ispdepressed. Normally the arm 96 is inlocking position wherein its holds the shaft 60 against rotation, butwhen the operator depresses the lever 101, thereby momentarilyenergizing the solenoid which pulls the arm 96 from locking position,whereupon the shaft 60 and parts carried thereby make one completerevolution, after which the arm 96 locks the clutch and shaft againstfurther rotation. y

Since the stripper 28is effectiveV only partly to remove the cutfed bagfrom the stretcher arms, means are provided to effect ,complete removalfrom the machine and such means comprise a conveyor carried by the innerend of the machine, as shown in Figs. 1 and 2. This conveyor comprises a'drive shaft 104, mounted in pillow blocks 105 Whichfarwewred am thereficalz iets @t1-these@ and; between the ends of `the shaft is a sheave106 connected,v through Vfbelts 108to4thesecond,oflthe two sheavesl64cfhendjf the shaftk 1'104"v and ink approximate alignment:Y lwithmthe lsprockets 1`68Qare of` rtheA motor `65,! cent to drivefs'prockets 110,.`

As the shaft 60 completes its 360 revolution, thesegment gear disengages the rack 34, thereby permitting the spring 36 toreturn it to retracted position.

In the meantime the conveyor continues to operate and when the stripper28 has carried the closed end of the cuifed bag to a position above orbeyond the shaft 114, then the lug 120 engages the projecting end of thereinforcement R to carry the bag along the guard rails and drop it at anappropriate place. All parts are now restored to original position andthe operation is repeated.

An ordinary operator may produce as many as 3,000 bags per eight-hourday, as compared with less than half that amount by hand. Furtheradvantages are that diiiiculties due to static are eliminated and linerbags of much lighter Weight may be used. Moreover, breakage or spoilageis reduced to a minimum.
